HEATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 787,748, dated A pr? 18, 1905.

Application filed Apiii 11, 1904. Serial No. 202,573.

To @ZZ whom, it' nanny concern:

Be it known that I, ERNST' GLANTZBERG, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Heating Systems, of which the following is afull, clear, and eXac't description.

This invention relates to improvements in heating' apparatus in which steam or hot water is employed as the heating' agent, and although in the description hereinafter given the term "steam is generally employed, it is to be understood that the word steamis to be used interchangeably with hot water, one being the equivalent of the other so far as the capabilities of the present invention are concerned.

The object of the invention is to provide a heating` system in which there may be as many individual heaters as desired, all supplied from a single boiler or source of steam, with arrangements whereby the steam may be controlled, preferably, at a point remote from `the individual heaters, so that the steam may enter only one heating-chamber of one or more of the heaters or both heating-chambers thereof, all to the end of providing adequate heat for any apartment or apartments, and more or less according to the temperature conditions and with no liability of overheating, and thus the steam-supply for the heating purposes will be economically applied and the occupant of the appartment to be heated need not concern himselfl with the control or regulation of the steam, although in addition to the steam-controlling arrangements operable in the boiler-room or remote from the apartment to be heated valves individual to the respective heaters or series of them may be provided for opening and closing the heaters to and from the passage of steam thereinto. A l

The parts and arrangements composing the steam-heating system are hereinafter fully described, in connection with the accompanying drawings, and set forth in the claims.

In the drawings, Figure l is a view in the nature of a diagram, showing series of heaters i'n 'several buildingsror apartments alll connected with a single source of steam-supply having valves and valve-controlling arrangements appertaining to each series of heaters and the different sets of heating-chambers therein. Fig. 2 is a sectional View of the lower portion of a heater or radiator such as may be advantageously embodied in the present heating system. Figs. 3 and 4 are perspective representations of special valveoperating means provided for the aforementioned radiator.

In the drawings, A A represent a series of heaters or radiators each having a compartment or heating-chamber t and a compartment or heating-chamber Z1 therein, one. thereof being separate or divided from the other. B represents a steam-boiler from which a steam-pipe C runs to connection with the main heating-chambers a of the several heaters A A, this pipe being of course branched within the building or room at which the series of heaters are located for the respective connections, and adjacent the several heaters is a pipe D, branched from the main steampipe C, the same having continuations or branches vconnecting into the secondary heating-chambers b of the several radiators A.

F and G represent valves in the main steampipe C and the branched steam-pipe D, having their locations between the junction of the two pipes and the chambers of the heaters with which these pipes are respectively connected, these said valves having diaphragm-motorsf and g of a very common and well-known description operably subject to the pressure of a motor fluid, such as compressed air, and the pipes f2 g2 are connected, respectively, with the diaphragmcases of the valve-motors fand g and with the receiver of an air-compressor E, each of these' pipes having a ,manually-operated controlling-valve f3- and g3, respectively. In addition to and back of the motor -controlled valvesf and g the main pipe Gand branchD preferably have provided therein hand-operated valves i and c'. By opening the valve f3 in the air-pipe f2 the motor f for the main steam-pipe valve F may be operated to open such valve and permit an access of steam into the main heating chamber of each of the IOO heaters A A of the series, or instead the valve g2 in the air-pipe g2 may be opened for giving an access of steam into the other compartment of each of the heaters of the series accordingly as considerable or a lessened degree of heat is desired, and where a maximum heat is desired both valves may be simultaneously opened, and by the provision of the valves /L and c', back oi' the motor-controlled valves Fand G, it becomes possible to prevent, as might be desirable at times, any steam entrance into either oi' the compartments of the heaters of the series, even although the motor-controlled valves might be opened.

It has not been deemed necessary herein to illustrate the usual return-conduits for the steam condensation, it being understood that proper provision therefor is to be made.

Description thus far has been given in connection with the series of heaters A comprised in the left-hand group and with the connections and appliances therefor, and next to the right thereof is shown another group of heaters A2, having heating-chambers a2 and Z22 therein, divided or separated the one from the other, and the branch C2 of the main steampipe C and subbranches of the branch C2 connecting the main steam-pipe C with the set of heating-chambers c2 in the several radiators A2, While a branch pipe D2 of the aforesaid pipe branch C2 connects the said branch C with the set of heating-chambers b2 in the several radiators A2, 'the primary branchC2 and the secondary branch D2 having between their junction and the respectively connected radiators, the valves F2G2 having valve-operating motors f" and g, with one of which motors an air-pipe has connection, said pipe being by its other end connected with the air-compressor E, a hand-operated valvej3 being provided in such pipe j', and a pipeg'1 has connection with the diaphragm-case of the valvecontrolling motor g, provided for the secondary branch D2, such pipe having, primarily, a connection with the receiver of the aircompressor, and in the example here illustrated, by being connected as a branch of the aforementioned pipe g2. By having at' least one of the valve-controlling motors appertaining to the pipe connections for the second group of heaters A2 pipeconnected with the compressed-air receiver by a pipe independent of and additional to either of the pipes f2 or g2 it becomes possible at a point ot' control remote from the group of heaters A2 to establish heat in the heating-chambers of the radiators A2 in a high or moderate degree, as may be desired, and for a different period of time than that for which heat may be established in the left-hand group of heaters, and in cxtension of the capabilities incidental to this invention a right-hand group of heaters A3 is shown, for which a branch C3 of the main steam-pipe C has connections through proper subbranches, and the motor-controlled valve F2 for the pipe C3 has connected to the motor thereof the air-pipe L', the same also having primarily a connection With the aircompressor receiver, and` as shown, byvhaving such pipe 7c connected into one of the air-pipes (here the one g2) operatively arranged in connection with the motors controlling the valves for the steam-supply pipes of the other group or groups of heaters.

As an example of the availability of the present invention for supplying economically steam or hot water heat to various customers, the left-hand group of heaters may be those comprised in a hotel or dwelling, the middle group of heaters those in an office-building, and the right-hand group of heaters those comprised in a warehouse. By opening the valves f3 and gor only opening the valve g2 the hotel may be heated, say, for the Wholey day of twenty-four hours at a maximum or an intermediate degree ol' heat, as may be required, and the Warehouse, the heating-chambers in which are of less heating capacity than those in the heaters A, may be heated for the same length of time at the considerably lower degree as predetermined in the installation of the heaters, and the heaters A2 in the olicebuilding may be controlled to heat in a maximum degree-say for ten hoursor during the time of occupany of the building by the opening of the valve 72, when by closingsuch valve the further heating by the group A2 will be under the control of the air-valve g3, so that if the conditions are such that the secondary heaters of the secondary chambers Z) of the heater group A should and are receiving steam the secondary chambers 62 of the heating group A2 will also receive steam, and

without attempting to describe or illustrate the variability and extent of and to which the invention may be carried out it is desired to bring clearly to notice that differently-located sets of heaters may be all supplied from a common heating source and so controlled that at the place of location of each set the heating may be more or less high, as desired, and the periodicity of the heating in the place of installation of one set of heaters may be different from that at the place oi' installation of the other set of heaters, although one controller for the valve-motors of pipes pertaining to several of the groups may be utilized to establish a moderate degree of heat in the heaters of several or all of the groups, the attainment of a maximum heat in any of the groups being by the manipulation of the controller for the valve-motor of the steam-su pply pipe or pipe branch pertaining to the heaters of the group in which the maximum heat is required.

Under certain phases of this invention novel arrangements exist, even although separate heaters or separate heating-chambers are provided only in one set or group in a given place,

'chambers, while a branch thereof connects the other set of heating-chambers, and a valve of suitable description is provided in the pipe or pipes connected with the different sets of heating-chambers located betweenthe junction of the main steam-pipe and the branch thereof. Nevertheless the extension of the idea of means whereby different sets or groups of heaters at different locations all supplied from a common source of'steam through a main feed-pipe and branches thereof together with controlling means whereby the degree of heat in the different groups of heaters and the period in which such degree of heat may be maintained variable in the different groups is novel and very desirable, as thereby enabling the most economical supplying of heat to different consumers according totheir varied needs, giving a maximum of heat where desired and a materially lessened degree of heat where desired, with no overheating at one place and under heating at another, and all with a most economical utilization of the steam in the steam-supply plant, and in a manner whereby no attendant at the place or places to be heated is required to control or regulate the heat thereat.

While the means for variably controlling the heat at the different locations is through the medium of the motors for the valves, having air-pipe connections with a compressed-air receiver and valves for opening and closing the air-pipes to render the valve-motors active or passive, as here particularly illustrated and described,other val ve-operating means may be depended upon than 'those just mentioned, whether the same be operable manually, mechanically, electrically, or thermostatically.

In Fig. 2 a form of heater or radiator is represented having the heating-chambers ce and therein connected by a passage m, having a valve 'n therefor, which may be usually closed, but which may be opened when desired, so that instead of havinga radiator with divided chambers dependent for its supply on respectively provided steam-pipe connections the radiator may be transformed into one adapted to receive steam for heating throughout its entire space, and therefore by providing individual radiators in a group of the kind last mentioned a person in a given room may acquire a full volume of steam in the particular radiator even although but one of the steamfeeding pipes connected thereto and to other heaters in the same group is opened, and in order that the valve o?, may be operated only by a person properly conversant with the steam regulation the stem n2 for the valve which screw-threads at 71.3 through a gland a* has its extremity ai constructed to be engaged only by a special key or wrench 0, the same having recesses or wards o2, specially formed to engage the projections n on the valve-stemy extremity a5; said extremity being inclosed within a socketed shield p. l
